Uwagi
Ten konstruktor tworzy CipherReference obiekt przy użyciu identyfikatora URI (Uniform Resource Identifier), który wskazuje zaszyfrowane dane. Obiekt jest następnie używany do przekazywania informacji referencyjnych CipherData dla obiektu.
Możesz użyć identyfikatora URI, aby wyznaczyć plik XML zawierający zaszyfrowane dane. Na przykład:
String uri = "http://www.woodgrovebank.com/document.xml";
Można również użyć częściowego identyfikatora URI, aby wyznaczyć, że tylko część dokumentu XML ma być szyfrowana. Załóżmy na przykład, że dokument XML o nazwie document.xml zawiera dwa MyForm
elementy, jak pokazano w poniższym przykładzie kodu XML:
<MyForm Id='Form1'>
<! -- Form data here -->
</MyForm>
<MyForm Id='Form2'>
<! -- Form data here -->
</MyForm>
Możesz zaszyfrować tylko zawartość w Form2
programie przy użyciu identyfikatora URI, takiego jak:
String uri = "http://www.woodgrovebank.com/document.xml#Form2";
